I called 0800 number and went through the process of unplugging cables restarting the unit but that worked only for 10 minutes and crashed again. They suggested to unplug all the cables and leave it for 6 hours to reset it to factory settings.
I don't think this will help. I am guessing it is a hard drive problem.
Anyone experienced the same problem? I hope they will just replace it for a new unit.
P.S. Sorry for my English, it's not my mother language.
